Embodiment Construction
[0025]An embodiment of the present invention is described in detail below.
[0026]FIG. 1 is a non-volatile memory circuit illustrating an embodiment of the present invention. Referring to FIG. 1, the non-volatile memory circuit according to the present invention is described below.
[0027]In this embodiment, as illustrated in FIG. 1, a P-channel non-volatile memory element 1 includes a floating gate and a control gate capacitively coupled to the floating gate. The control gate is connected to a divided voltage output of a resistor divider 4 including a first resistor 2 and a second resistor 3 for dividing a voltage difference between a power supply voltage and a ground voltage, and is also connected to a P-channel switch transistor 5 connected in parallel to the first resistor 2 and an N-channel switch transistor 6 connected in parallel to the second resistor 3.
[0028]Next, a description is given of the operation of the non-volatile memory circuit according to this embodiment.
